" In conventionally constructed-machines ofthe above mentioned type, it wi-11-be understoodthat the mandrels are of greater length than'tha-tfiofi the" jumbo roll i to wind the webdrawn" from the jumbo roll "thereon. The-ju1hbo roll's now: are usually eighty-one inches long and the web unwound'therefrom is slit; so as to-provide-eight een strips each-four and one-half inches-wide from which toilet paper rolls' are'wound." *"It therefore follows that each mandrl is at leasteighty-one inches long between-bearing Supports therefor, with the result the mandrelscu iteread ily flex laterally at their centers.
